La Teniente takes a cinematic approach to scripted TV, using locations throughout Mexico and top Spanish-language TV actors as it depicts the adventures of a Special Operations unit of the Mexican Navy. Centering on Mexican Naval graduate Lieutenant Roberta Ballesteros (María Fernanda Yepes), the series shows the challenges facing her immediate and emotional entry into the elite Special Operations unit after a violent tragedy occurs to the group. The series follows her assimilation into the unit, which is filled with drama, action, love triangles, heroes and family.
